That is not completely clear to me. open(2) and openat(2) get a O_EXEC
flag, but I did not found other reference of it: fexecve(2)
specification does explicitely require a fd open with O_EXEC.
We could have such a limitation, though: it requires real cooperation
between two the two processes if the opener needs to use O_EXEC and the
executer needs to call fexecve(2)
